Our 1.7mm to 2.1mm DC Adapter Cable provides a reliable bridge between standard power supplies and specialized portable electronics. This flexible adapter allows you to repurpose common 2.1mm barrel power bricks for devices requiring a smaller 1.7mm micro-DC input.
Precision 1.7mm Output Plug: Features a 1.7mm outer diameter DC male plug, specifically designed for compatible netbooks, small tablets, and specialized electronic devices.
Standard 2.1mm Input Socket: Equipped with a universal 2.1mm x 5.5mm DC female socket, ensuring compatibility with the vast majority of consumer power adapters.
Yellow-Tip Identification: The 1.7mm male connector is finished with a distinct yellow insulator tip for easy visual size verification.
Stress-Reducing Flexible Lead: The short cable design prevents the rigid leverage that can occur with one-piece adapters, protecting your device's delicate internal power port from physical damage.
Reinforced Molded Ends: Built with durable, integrated strain relief on both the plug and socket to withstand repeated bending and daily use.
Tactile Grip Housing: The 2.1mm socket features a textured, anti-slip surface for secure handling and easy disconnection.
Connector A (Output): 1.7mm DC Male Plug (Yellow Tip).
Connector B (Input): 2.1mm x 5.5mm DC Female Socket.
Wiring: High-Efficiency Parallel Copper Core.
Jacket Material: Impact-Resistant Matte Black PVC.
Polarity: Straight-Through (Typically Center-Positive).
Color: Professional Stealth Black.
Legacy Device Power: Connect modern high-quality power supplies to older portable devices that use the 1.7mm barrel standard.
Netbook & Tablet Charging: Compatible with various specialized micro-laptops and charging docks requiring a 1.7mm input.
Electronic Bench Work: A necessary tool for technicians needing to adapt bench power supplies to devices with non-standard micro-ports.
Is this the same as a 0.7mm plug? No. While they look similar, this plug has a 1.7mm outer diameter. If you need the even smaller version, please check our 0.7mm DC Plug adapter.
Does this regulate the voltage? This is a physical adapter cable only. It does not change the voltage. Please ensure your power supply outputs the exact voltage your device requires before connecting.
Is the yellow tip a specific size standard? Yes. In the world of DC barrel connectors, the yellow insulator tip is the industry standard color-coding for identification of micro-sizes like 1.7mm or 0.7mm.
